It tells with precision and detail where each bit goes. The DES standard ( FIPS 46-3) is actually a rather straightforward description of DES. So I would like to know if someones has a PDF or any other real mathematical explanation of the DES encryption system. ![]() I know this kind of encryption systems have a lot to do with the mathematical concept of a field. I need a mathematical explanation of what does the DES encryption system really do.
